Product Overview

The LT1787IMS8#PBF is a complete micropower precision high side Current Sense Amplifier for use with power monitoring and battery-operated systems. The LT1787 monitor bidirectional currents via the voltage across an external sense resistor. A current or voltage output indicates the direction and magnitude of the sense current. The LT1787 delivers greater than a 12-bit dynamic range with ultralow 40µV input offset voltage compared to a typical 250mV full scale input voltage. A fixed gain of 8 is set by on board precision resistors. Input signal filtering is easily implemented with a capacitor between the FIL-and FIL+ pins. The LT1787 operates from 2.5 to 36V total supply voltage. It has a PSRR in excess of 120dB.
